Pure and affordable drinking water for a whole region

Sliding gate valves are optimising Belgium’s largest facility for RO water purification.

Veolia Water Technologies has built an ultra-modern plant to produce drinking water in Ostend, Belgium. In a multi-stage filtration process, the local water supplier is now producing drinking water of excellent quality – far above the statutory requirements. At critical points of the process – during reverse osmosis, filtration with activated carbon and remineralisation of the water – sliding gate valves made by Schubert & Salzer Control Systems are responsible for regulating pressure and flow rate.

The water supplier, FARYS, produces drinking water for the city of Ostend and its surrounding area from the brackish water in the Bruges-Ostend Canal. In the current development stage of the waterworks built by Veolia Water Technologies, up to 1,200 m3 of drinking water per hour can be fed directly into the pipe network. The plant constructed by the leading specialist for water treatment is the largest Belgian drinking water production facility using RO technology and the production speed is among the fastest in the world. It is also unique that [...]

In the multi-stage filter process, up to 1,200 cubic metres of drinking water per hour can be extracted from the brackish water of the Bruges-Ostend Canal.

 

Sliding gate valves from Schubert & Salzer with a nominal size of 150 millimetres control the pressure at the outlet of the total of 12 reverse osmosis units. Striking: the compact dimensions of the valve and electropneumatic actuator.
